Stihl 023 fuel vent

[alex_m]

Hi guys, just acquired an old 023 and noticed that what seems to be the fuel vent (small piece of hose coming out the top of tank with two screws inside) is leaking fuel when on its side. I've turned the saw upside down and can see the fuel going round the turns in the screws then out the end.

Is this normal?

 

Cheers

The screws act like a one way valve. Air in no fuel out.

 

Try moving them along the pipe a small amount so the thread pick up on new pipe. See if it cures it.

 

Other than that a new pipe.

Ok cheers, where could i get a new pipe with the screws?

Not sure try any dealer on here. Need to check an IPL to see if any other fit.
